桥梁薄壁墩裂缝成因分析及预防

Analysis and prevention on causes of cracks in the bridge thinwall pier

针对薄壁墩施工过程中容易产生裂缝的问题,通过建立有限元模型,研究了施工温度对薄壁墩裂缝的影响,并进一步对薄壁墩施工过程中开裂现象提出有效防治措施,以提高桥梁的耐久性及外观质量。

Aiming at the problem that the cracks easily happens during the construction of thin-wall pier, through building finite dement model, the paper studies the influence of the construction temperature on the thin-wall pier cracks, and further proposes the effective prevention measures for the cracking during the thin-wall pier construction, so as to improve the durability and apparent quality of the bridge .
